| 摘 要： | 建立了高效液相色谱-紫外光谱法测定聚氨酯扩链剂氢醌-双(β-羟乙基)醚(HQEE)工业品中HQEE主含量和对苯二酚残留的方法。在氰基柱上,以甲醇-水-1%乙酸溶液(体积比10∶50∶40)为流动相,流速1.0 mL/min时,HQEE、对苯二酚及其他相关杂质得到良好分离,紫外光谱285 nm检测。方法简便、快捷,结果准确可靠,在工业生产中可有效地指导HQEE合成过程的质量控制。 |
| 关 键 词： | 氢醌-双(β-羟乙基)醚(HQEE) 扩链剂 对苯二酚 高效液相色谱 紫外光谱检测 |

| Abstract: | A high performance liquid chromatography-ultraviolet spectrometry(HPLC-UV) method has been developed for determination of hydroquinone bis(2-hydroxyethyl)ether(HQEE) and hydroquinone in industrial HQEE,a kind of polyurethane chain-extender.Separation of HQEE,hydroquinone and other relative impurities was achieved on a LiChrospher CN column by using methanol-water-1% aqueous acetic acid solution(10∶50∶40,V/V/V) as the mobile phase at a flow rate of 1.0 mL/min.Detection was operated by UV absorption at a wavelength of 285 nm.The method is rapid,reliable and suitable for effective control and improving HQEE quality in synthesis. |
| Keywords: | hydroquinone bis(2-hydroxyethyl)ether(HQEE) chain-extender hydroquinone high performance liquid chromatography ultraviolet-visible spectrophotometric detection |
